S2A Equivalent & Substitute Parts Reference

Part Overview

The S2A is a general-purpose rectifier diode manufactured by SMC Diode Solutions, rated for 50 V DC reverse voltage and 2 A average rectified current in a surface mount SMB (DO-214AA) package. This component is classified as Active product status and is ROHS3 compliant. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative packaging configurations are required for specific applications.

Substitute Part Grouping Explanation

Substitute parts for the S2A are grouped into two categories based on allowed electrical and mechanical parameters:

Category 1: Direct Package Equivalents (SMB DO-214AA) Parts ES2A-13-F and S2A_R1_00001 maintain the same package configuration (DO-214AA, SMB) and satisfy the core electrical requirements: 50 V reverse voltage rating and 2 A average rectified current. These parts are mechanically and electrically interchangeable in applications where the SMB package footprint is specified.

Category 2: Alternative Package Configuration (SMA DO-214AC) Part ES2AA-13-F provides electrical equivalence (50 V, 2 A) but uses an alternative surface mount package (DO-214AC, SMA). This substitute is applicable only when the circuit design permits SMA package substitution or when SMA footprint availability is preferred.

Key Parameters Determining Substitution:

• Voltage - DC Reverse (Vr) (Max): 50 V (required match)
• Current - Average Rectified (Io): 2 A (required match)
• Mounting Type: Surface Mount (required match)
• Operating Temperature Range: -55°C to 150°C (required match)
• RoHS3 Compliance: Required for all substitutes

Parameter Comparison

Engineering Selection Recommendations

For SMB Package Requirement (DO-214AA): ES2A-13-F and S2A_R1_00001 are direct mechanical and electrical substitutes for the S2A. Both maintain the SMB package footprint and satisfy all core electrical parameters. ES2A-13-F features fast recovery characteristics (25 ns trr) compared to the S2A standard recovery (2.5 µs trr), resulting in lower forward voltage (920 mV vs. 1.1 V @ 2 A). S2A_R1_00001 maintains identical forward voltage and recovery speed classification as the S2A while offering improved reverse leakage performance (1 µA vs. 5 µA @ 50 V). All three parts are ROHS3 compliant and Active product status.

For SMA Package Requirement (DO-214AC): ES2AA-13-F provides electrical equivalence with the S2A but requires circuit board redesign to accommodate the SMA package footprint. This substitute is applicable only when the design permits alternative package geometry. ES2AA-13-F shares the fast recovery characteristics and lower forward voltage of ES2A-13-F and maintains ROHS3 compliance and Active product status.

Compliance and Regulatory Considerations: All substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited). The S2A and S2A_R1_00001 are REACH Affected; ES2A-13-F and ES2AA-13-F are REACH Unaffected. All parts carry ECCN EAR99 classification and HTSUS code 8541.10.0080.

Frequently Asked Questions (FAQ)

Q: Can ES2A-13-F be used as a direct replacement for S2A in existing circuit boards? A: Yes. ES2A-13-F maintains the same SMB (DO-214AA) package footprint and satisfies all core electrical requirements: 50 V reverse voltage, 2 A average rectified current, and -55°C to 150°C operating temperature range. No circuit board redesign is required.

Q: What is the difference between ES2A-13-F and ES2AA-13-F? A: The primary difference is package configuration. ES2A-13-F uses SMB (DO-214AA) package; ES2AA-13-F uses SMA (DO-214AC) package. Both share identical electrical ratings and performance characteristics. Circuit board redesign is required to substitute between these two parts.

Q: Why does ES2A-13-F have lower forward voltage (920 mV) compared to S2A (1.1 V)? A: ES2A-13-F is classified as fast recovery (≤500ns trr, 25 ns typical) while S2A is standard recovery (>500ns trr, 2.5 µs typical). Fast recovery diodes typically exhibit lower forward voltage drop at the same current rating.

Q: Is S2A_R1_00001 a suitable substitute for high-frequency switching applications? A: S2A_R1_00001 maintains standard recovery speed classification (>500ns) identical to the S2A. For high-frequency switching applications requiring fast recovery characteristics, ES2A-13-F or ES2AA-13-F are more appropriate selections.

Q: Are all substitute parts available in the same packaging format (Tape & Reel)? A: The S2A is supplied in standard packaging; ES2A-13-F, ES2AA-13-F, and S2A_R1_00001 are all available in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: What is the reverse leakage performance difference between S2A and S2A_R1_00001? A: S2A_R1_00001 exhibits superior reverse leakage performance at 1 µA @ 50 V compared to S2A at 5 µA @ 50 V. This lower leakage may provide benefits in low-power or precision applications.

Q: Can these diodes be used interchangeably in rectification circuits? A: Yes, within the specified electrical parameters. All substitute parts maintain 50 V reverse voltage rating and 2 A average rectified current. Circuit performance differences may occur due to variations in forward voltage and recovery time; these should be evaluated based on specific application requirements.
